e9dd619d44 From John Dyson: Disabled multi-sector I/O. It is causing some people
problems.

f6b04d2bfb Changes from John Dyson and myself:
Fixed remaining known bugs in the buffer IO and VM system.

vfs_bio.c:
Fixed some race conditions and locking bugs. Improved performance
by removing some (now) unnecessary code and fixing some broken
logic.
Fixed process accounting of # of FS outputs.
Properly handle NFS interrupts (B_EINTR).

(various)
Replaced calls to clrbuf() with calls to an optimized routine
called vfs_bio_clrbuf().

(various FS sync)
Sync out modified vnode_pager backed pages.

ffs_vnops.c:
Do two passes: Sync out file data first, then indirect blocks.

vm_fault.c:
Fixed deadly embrace caused by acquiring locks in the wrong order.

vnode_pager.c:
Changed to use buffer I/O system for writing out modified pages. This
should fix the problem with the modification date previous not getting
updated. Also dramatically simplifies the code. Note that this is
going to change in the future and be implemented via VOP_PUTPAGES().

vm_object.c:
Fixed a pile of bugs related to cleaning (vnode) objects. The performance
of vm_object_page_clean() is terrible when dealing with huge objects,
but this will change when we implement a binary tree to keep the object
pages sorted.

vm_pageout.c:
Fixed broken clustering of pageouts. Fixed race conditions and other
lockup style bugs in the scanning of pages. Improved performance.

4fb0b0de3e Implement a simple hook (or hack?) to allow graphics device console
drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.

Implement the logic to use this hook from within pcvt.  (I'm sure
Søren will do the syscons part RSN).

I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour.  It's hard to track bugs without the console and DDB
available. :-/

b4fff2ae1a Patch from Greg Ansley:
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect.  And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.

If you look at the code you will discover the the index *k* is added to
the pointer *cp* and the used AGAIN as a subscript.

5743c01c3f Major overhaul of the aic7xxx driver:
- Report valid residual byte counts.  We actually pause the sequencer
	  when the residual is non-zero.  I thought about using DMA to do this,
	  bus sequencer program space is tight.

	- Fix embarassing off by one error in the computation of a 2's
	  compliment variable.  This was most likely the cause of the
	  many problems reported with the tagged queuing code.

	- Handle "MAX_SYNC" as a special case (ie we are the ones starting
	  the sync negotiation sequence).  This was done so that the target
	  scratch area can be initialed to 0 offset (asyncronous transfers)
	  safely.  The initialization to 0 (was 15) is necessary since in
	  some cases a Wide negotiation could run into problems if SCSIRATE
	  was set wrong and we went into data(in/out).

	- Trim the DMA routines a little by using some procedures.  Net
	  effect is more functionality with 3 less instructions after this
	  update.

	- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
	  last SG block.  It has no effect in the 8bit bus configuration,
	  but in the Wide configuration ensures that the overlap byte is
	  held in the SCSI block if the transfer is odd so it will end
	  up in the next SG (the correct behavior).

c5e0851d47 Major overhaul of the aic7xxx driver:
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
	  of guessing the right type.

	- Add pause variable to the ahc struct to better handle the different
	  interrupt types and pausing the sequencer.

	- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
	  register in newer Adaptec documentation, so use their name for it.

	- Report valid residual byte counts.

	- Don't mess with the target scratch areas > id 8 on single, narrow,
	  channel devices.  The BIOS does a checksum of this area and can
	  flip out if we zero it out.

	- Initialize the sequencer FLAGS scratch ram variable in the single
	  channel devices to 0.  This was the cause of the annoying warning
	  where we would get a cmdcmplt the first time we did any type of
	  transfer negotiation with no valid scb.  It also fixes the problem
	  that looked like the INTSTAT register wasn't clearing fast enough.
	  This only showed up on 294x cards, not motherboard aic7870s.

	- Add the AHC_AIC7870 type and use it as the superset of aic7870
	  based controllers.

	- clear the sync offset section of the targ scratch area so that
	  we default to asyncronous transfers.  This was only a problem
	  for wide controllers because there was a scenario where the
	  offset wouldn't get updated before a data(out/in) phase would
	  occur.  This required some change in the sequencer code since we
	  were depending on this field to hold the rate to negotiate.

	- allow sync and wide negotiated commands to be tagged (the sequencer
	  now handles this properly).

ca9301398c This sl enhancement helps to keep serial line (modem) connection alive.
It is common case when modem hangs with carier on but don't
receive anything from another side.
This thing commonly healed with hangup and redialing.
Enhancements below allows to determine when such action
is needed and inform attach program with SIGURG signal.
There two ioctls set: outfill and keepalive, used from both
sides of connection. Outfill repeatedly sends FRAME_END with
specified timeout (i.e. 40 seconds). It is needed to get input on
other side even if no user activity on slip line currently.
Keepalive checks FRAME_ENDs from other side, and if no one
got in specified timeout (i.e. 60 seconds, max modem retrain time),
send SIGURG to attach program.
I plan to add code to slattach to handle this thing too.

to have this occur all the time - especially when most people will never

702c5e7e17 ttyinput() fixes:
1) Preserve old buffer contents when input buffer overflows.

Old code clear buffer and rewrite it again, if !MAXBEL
(for MAXBEL it does right thing :-).
F.e. if you type too long string, last chars passed,
not first ones as expected.
Moreover, it flush output queue too in this case without any needs.

2) Don't do IXOFF, if IGNCR and c==\r, ignore completely.

3) If PARMRK is active and !ISTRIP and char == 0377
put yet one 0377 to distinguish it from parity mark sequence.
POSIX standard (thanx Bruce).

2cad35d11b Several fixes to help "raw" tty mode work correctly with
BREAK/parity/framing errors.
Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*
is set in iflag. It helps "raw" mode works even IGN* is set.
2) Zero parity (if INPCK) and framing directly in buffer
before passing it to b_to_q() in "raw" mode.
Efficency:
interrupt level: if no error occurse, only two "test" commands added
"raw" mode: buf scan incc times for parity/framing added

- ignore the partition table if it is identical with the bogus one in
  /usr/src/sys/i386/boot/biosboot/start.S.  Honoring the bogus size
  field was fatal.  The error is detected but other compatibilty
  cruft weakens the error handling too much for this case.
- weaken the partition entry checking to allow the following treatments
  of C/H/S addresses when C should be >= 1024:
    (1) allow C = 1023, H = max, S = max.
    (2) allow C to be correct modulo 1024.
  Other compatibilty cruft weakens the error handling to allow all
  C/H/S addresses, but there too many errors were reported.

Improve error messages:
- print C/H/S addresses if relevant.
- distinguish primary partition table from extended partition tables.
- don't use diskerr() except for i/o errors.

8673e05a9a Completely new PCI code:
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

4e83f749ec Don't sync the inode date changes of character special devices
during the FS sync. The system would appear to hang momentarily
if there was a large backlog of I/O. This is because the vnode
remains locked during the output - preventing normal character
I/O. The problem was exacerbated by the FFS contiguous block
allocation fixes and a semi-broken disksort(). The inode/date
will still be synced during a normal FS dismount and whenever
the inode is changed for other reasons.

for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.
